请帮我润色一下下边双引号里边的这段话，注意不是翻译，让他读起来更像是论文里边的句子。“When the kernel size is 7×7, as with convolution where the kernel size is 3×3, the two outputs of MB are not fully pipelined. These two outputs need to accumulate 6 and 2 clock cycles respectively, but the clock ratio of their outputs is still 3:1, which means that the DSP utilization can still be maintained at a very high level. A proper zero-setting is still necessary for convolution core to obtain correct and error-free accumulation results.”

当核大小为7×7时，与卷积（其中核大小为3×3）相同，MB 的两个输出不能完全流水线处理。这两个输出分别需要累积6和2个时钟周期，但是它们输出的时钟比例仍然为3：1，这意味着 DSP 的利用率仍然可以保持在非常高的水平。对卷积核进行适当的清零仍然是必要的，以获得正确无误的累积结果。
